BACKGROUND OF THE INVENTION

Pancreatic enzyme replacement therapy (PERT) finds use in the treatment of pancreatic enzyme insufficiency (PEI). Various disorders, including pancreatitis, cystic fibrosis, celiac disease, inflammatory bowel disease, and pancreatic cancer can lead to PEI, as a consequence of decreased secretion of pancreatic enzymes into the duodenum. This results in poor digestion of food, inadequate absorption of fat, proteins, carbohydrates, and vitamins by the intestines, which can lead to malnutrition. Although orally administered PERT treatments are currently available, the condition may not be alleviated in some people, due to insufficient activity of the PERT in the gastrointestinal tract and/or insufficient patient compliance with the therapy due to the significant pill burden associated with current treatment protocols. In some cases, the coefficient of fat absorption (CFA) and/or coefficient of nitrogen absorption (CNA) is inferior to that of healthy patients, resulting in weight loss and other health concerns. Thus, a need remains in the art for improved PERT treatments.

The term “engineered,” “recombinant,” “non-naturally occurring,” and “variant,” when used with reference to a cell, a polynucleotide or a polypeptide refers to a material or a material corresponding to the natural or native form of the material that has been modified in a manner that would not otherwise exist in nature or is identical thereto but produced or derived from synthetic materials and/or by manipulation using recombinant techniques.

Recombinant polypeptides can be produced using any suitable methods known the art. Genes encoding the wild-type polypeptide of interest can be cloned in vectors, such as plasmids, and expressed in desired hosts, such as E. coli, S. cerevisiae, etc. Variants of recombinant polypeptides can be generated by various methods known in the art. Indeed, there is a wide variety of different mutagenesis techniques well known to those skilled in the art. In addition, mutagenesis kits are also available from many commercial molecular biology suppliers. Methods are available to make specific substitutions at defined amino acids (site-directed), specific or random mutations in a localized region of the gene (regio-specific), or random mutagenesis over the entire gene (e.g., saturation mutagenesis). Numerous suitable methods are known to those in the art to generate enzyme variants, including but not limited to site-directed mutagenesis of single-stranded DNA or double-stranded DNA using PCR, cassette mutagenesis, gene synthesis, error-prone PCR, shuffling, and chemical saturation mutagenesis, or any other suitable method known in the art. Non-limiting examples of methods used for DNA and protein engineering are provided in the following patents: U.S. Pat. No. 6,117,679; U.S. Pat. No. 6,420,175; U.S. Pat. No. 6,376,246; U.S. Pat. No. 6,586,182; U.S. Pat. No. 7,747,391; U.S. Pat. No. 7,747,393; U.S. Pat. No. 7,783,428; and U.S. Pat. No. 8,383,346. After the variants are produced, they can be screened for any desired property (e.g., high or increased activity, or low or reduced activity, increased thermal activity, increased thermal stability, and/or acidic pH stability, etc.). In some embodiments, “recombinant lipase polypeptides” (also referred to herein as “engineered lipase polypeptides,” “variant lipase enzymes,” and “lipase variants”) find use.

As used herein, “wild-type” and “naturally-occurring” refer to the form found in nature. For example, a wild-type polypeptide or polynucleotide sequence is a sequence present in an organism that can be isolated from a source in nature and which has not been intentionally modified by human manipulation.

As used herein, “coding sequence” refers to that part of a nucleic acid (e.g., a gene) that encodes an amino acid sequence of a protein.

The term “percent (%) sequence identity” is used herein to refer to comparisons among polynucleotides and polypeptides, and are determined by comparing two optimally aligned sequences over a comparison window, wherein the portion of the polynucleotide or polypeptide sequence in the comparison window may comprise additions or deletions (i.e., gaps) as compared to the reference sequence for optimal alignment of the two sequences. The percentage may be calculated by determining the number of positions at which the identical nucleic acid base or amino acid residue occurs in both sequences to yield the number of matched positions, dividing the number of matched positions by the total number of positions in the window of comparison and multiplying the result by 100 to yield the percentage of sequence identity. Alternatively, the percentage may be calculated by determining the number of positions at which either the identical nucleic acid base or amino acid residue occurs in both sequences or a nucleic acid base or amino acid residue is aligned with a gap to yield the number of matched positions, dividing the number of matched positions by the total number of positions in the window of comparison and multiplying the result by 100 to yield the percentage of sequence identity. Those of skill in the art appreciate that there are many established algorithms available to align two sequences. Optimal alignment of sequences for comparison can be conducted, e.g., by the local homology algorithm of Smith and Waterman (Smith and Waterman, Adv. Appl. Math., 2:482 [1981]), by the homology alignment algorithm of Needleman and Wunsch (Needleman and Wunsch, J. Mol. Biol., 48:443 [1970), by the search for similarity method of Pearson and Lipman (Pearson and Lipman, Proc. Natl. Acad. Sci. USA 85:2444 [1988]), by computerized implementations of these algorithms (e.g., GAP, BESTFIT, FASTA, and TFASTA in the GCG Wisconsin Software Package), or by visual inspection, as known in the art. Examples of algorithms that are suitable for determining percent sequence identity and sequence similarity include, but are not limited to the BLAST and BLAST 2.0 algorithms, which are described by Altschul et al. (See, Altschul et al., J. Mol. Biol., 215: 403-410 [1990]; and Altschul et al., Nucleic Acids Res., 3389-3402 [1977], respectively). Software for performing BLAST analyses is publicly available through the National Center for Biotechnology Information website. This algorithm involves first identifying high scoring sequence pairs (HSPs) by identifying short words of length W in the query sequence, which either match or satisfy some positive-valued threshold score T when aligned with a word of the same length in a database sequence. T is referred to as, the neighborhood word score threshold (See, Altschul et al., supra). These initial neighborhood word hits act as seeds for initiating searches to find longer HSPs containing them. The word hits are then extended in both directions along each sequence for as far as the cumulative alignment score can be increased. Cumulative scores are calculated using, for nucleotide sequences, the parameters M (reward score for a pair of matching residues; always >0) and N (penalty score for mismatching residues; always <0). For amino acid sequences, a scoring matrix is used to calculate the cumulative score. Extension of the word hits in each direction are halted when: the cumulative alignment score falls off by the quantity X from its maximum achieved value; the cumulative score goes to zero or below, due to the accumulation of one or more negative-scoring residue alignments; or the end of either sequence is reached. The BLAST algorithm parameters W, T, and X determine the sensitivity and speed of the alignment. The BLASTN program (for nucleotide sequences) uses as defaults a wordlength (W) of 11, an expectation (E) of 10, M=5, N=−4, and a comparison of both strands. For amino acid sequences, the BLASTP program uses as defaults a wordlength (W) of 3, an expectation (E) of 10, and the BLOSUM62 scoring matrix (See, Henikoff and Henikoff, Proc. Natl. Acad. Sci. USA 89:10915 [1989]). Exemplary determination of sequence alignment and % sequence identity can employ the BESTFIT or GAP programs in the GCG Wisconsin Software package (Accelrys, Madison Wis.), using default parameters provided.

As used herein, “reference sequence” refers to a defined sequence used as a basis for a sequence comparison. A reference sequence may be a subset of a larger sequence, for example, a segment of a full-length gene or polypeptide sequence. Generally, a reference sequence is at least 20 nucleotide or amino acid residues in length, at least 25 residues in length, at least 50 residues in length, at least 100 residues in length or the full length of the nucleic acid or polypeptide. Since two polynucleotides or polypeptides may each (1) comprise a sequence (i.e., a portion of the complete sequence) that is similar between the two sequences, and (2) may further comprise a sequence that is divergent between the two sequences, sequence comparisons between two (or more) polynucleotides or polypeptide are typically performed by comparing sequences of the two polynucleotides or polypeptides over a “comparison window” to identify and compare local regions of sequence similarity. In some embodiments, a “reference sequence” can be based on a primary amino acid sequence, where the reference sequence is a sequence that can have one or more changes in the primary sequence. “Comparison window” refers to a conceptual segment of at least about 20 contiguous nucleotide positions or amino acids residues wherein a sequence may be compared to a reference sequence of at least 20 contiguous nucleotides or amino acids and wherein the portion of the sequence in the comparison window may comprise additions or deletions (i.e., gaps) of 20 percent or less as compared to the reference sequence (which does not comprise additions or deletions) for optimal alignment of the two sequences. The comparison window can be longer than 20 contiguous residues, and includes, optionally 30, 40, 50, 100, or longer windows.

“Corresponding to”, “reference to” or “relative to” when used in the context of the numbering of a given amino acid or polynucleotide sequence refers to the numbering of the residues of a specified reference sequence when the given amino acid or polynucleotide sequence is compared to the reference sequence. In other words, the residue number or residue position of a given polymer is designated with respect to the reference sequence rather than by the actual numerical position of the residue within the given amino acid or polynucleotide sequence. For example, a given amino acid sequence, such as that of an engineered lipase, can be aligned to a reference sequence by introducing gaps to optimize residue matches between the two sequences. In these cases, although the gaps are present, the numbering of the residue in the given amino acid or polynucleotide sequence is made with respect to the reference sequence to which it has been aligned.

As used herein, “mutation” refers to any change in a polypeptide or polynucleotide sequence. It is intended to encompass any number (i.e., one or more) of substitutions, insertions, deletions, and/or rearrangements present in a sequence (i.e., as compared to the starting or reference sequence). Thus, mutations in sequences result in the production of variant polypeptides (e.g., variant or recombinant lipases), as provided herein.

As used herein, “amino acid difference” or “residue difference” refers to a difference in the amino acid residue at a position of a polypeptide sequence relative to the amino acid residue at a corresponding position in a reference sequence. The positions of amino acid differences generally are referred to herein as “Xn,” where n refers to the corresponding position in the reference sequence upon which the residue difference is based. For example, a “residue difference at position X92 as compared to SEQ ID NO: 2” refers to a difference of the amino acid residue at the polypeptide position corresponding to position 92 of SEQ ID NO: 2. Thus, if the reference polypeptide of SEQ ID NO: 2 has a threonine at position 92, then a “residue difference at position X92 as compared to SEQ ID NO:2” means there is an amino acid residue other than threonine at the position of the polypeptide corresponding to position 92 of SEQ ID NO: 2 (e.g., T92A). In most instances herein, the specific amino acid residue difference at a position is indicated as “XnY” where “Xn” specified the corresponding position as described above, and “Y” is the single letter identifier of the amino acid found in the engineered polypeptide (i.e., the different residue than in the reference polypeptide). In some instances (e.g., in Table 4-1, 4-2, 4-3, 4-4, 4-5, 4-6, 4-7, and/or 5-1), the present disclosure also provides specific amino acid differences denoted by the conventional notation “AnB”, where A is the single letter identifier of the residue in the reference sequence, “n” is the number of the residue position in the reference sequence, and B is the single letter identifier of the residue substitution in the sequence of the engineered polypeptide. In some instances, a polypeptide of the present disclosure can include one or more amino acid residue differences relative to a reference sequence, which is indicated by a list of the specified positions where residue differences are present relative to the reference sequence. In some embodiments, where more than one amino acid can be used in a specific residue position of a polypeptide, the various amino acid residues that can be used are separated by a “/” (e.g., X2H/X2M/X2T or X2H/M/T or E2H/M/T). In some embodiments, the enzyme variants comprise more than one substitution. These substitutions are separated by a slash for ease in reading (e.g., Y27V/F385P). The present application includes engineered polypeptide sequences comprising one or more amino acid differences that include either/or both conservative and non-conservative amino acid substitutions.

As used herein, “conservative amino acid substitution” refers to a substitution of a residue with a different residue having a similar side chain, and thus typically involves substitution of the amino acid in the polypeptide with amino acids within the same or similar defined class of amino acids. By way of example and not limitation, an amino acid with an aliphatic side chain may be substituted with another aliphatic amino acid (e.g., alanine, valine, leucine, and isoleucine); an amino acid with hydroxyl side chain is substituted with another amino acid with a hydroxyl side chain (e.g., serine and threonine); an amino acids having aromatic side chains is substituted with another amino acid having an aromatic side chain (e.g., phenylalanine, tyrosine, tryptophan, and histidine); an amino acid with a basic side chain is substituted with another amino acid with a basis side chain (e.g., lysine and arginine); an amino acid with an acidic side chain is substituted with another amino acid with an acidic side chain (e.g., aspartic acid or glutamic acid); and/or a hydrophobic or hydrophilic amino acid is replaced with another hydrophobic or hydrophilic amino acid, respectively.

As used herein, “non-conservative substitution” refers to substitution of an amino acid in the polypeptide with an amino acid with significantly differing side chain properties. Non-conservative substitutions may use amino acids between, rather than within, the defined groups and affects (a) the structure of the peptide backbone in the area of the substitution (e.g., proline for glycine) (b) the charge or hydrophobicity, or (c) the bulk of the side chain. By way of example and not limitation, an exemplary non-conservative substitution can be an acidic amino acid substituted with a basic or aliphatic amino acid; an aromatic amino acid substituted with a small amino acid; and a hydrophilic amino acid substituted with a hydrophobic amino acid.

As used herein, “deletion” refers to modification to the polypeptide by removal of one or more amino acids from the reference polypeptide. Deletions can comprise removal of 1 or more amino acids, 2 or more amino acids, 5 or more amino acids, 10 or more amino acids, 15 or more amino acids, or 20 or more amino acids, up to 10% of the total number of amino acids, or up to 20% of the total number of amino acids making up the reference enzyme while retaining enzymatic activity and/or retaining the improved properties of an engineered enzyme. Deletions can be directed to the internal portions and/or terminal portions of the polypeptide. In various embodiments, the deletion can comprise a continuous segment or can be discontinuous.

As used herein, “insertion” refers to modification to the polypeptide by addition of one or more amino acids from the reference polypeptide. Insertions can be in the internal portions of the polypeptide, or to the carboxy or amino terminus. Insertions as used herein include fusion proteins as is known in the art. The insertion can be a contiguous segment of amino acids or separated by one or more of the amino acids in the naturally occurring polypeptide.

As used herein, an asterisk (*) used in the context of a polynucleotide sequence indicates the presence of a stop codon within the polynucleotide sequence. In some embodiments, the variant proteases are truncated, as compared to the starting or reference sequence, due to the presence of stop codons.

A “functional fragment” and a “biologically active fragment” are used interchangeably herein refers to a polypeptide that has an amino-terminal and/or carboxy-terminal deletion(s) and/or internal deletions (e.g., the sequence is truncated), but where the remaining amino acid sequence is identical to the corresponding positions in the sequence to which it is being compared (e.g., a full-length engineered lipase of the present invention) and that retains substantially all of the activity of the full-length polypeptide.

As used herein, “isolated polypeptide” refers to a polypeptide that is substantially separated from other contaminants that naturally accompany it (e.g., protein, lipids, and polynucleotides). The term embraces polypeptides that have been removed or purified from their naturally-occurring environment or expression system (e.g., host cell or in vitro synthesis). The recombinant lipase polypeptides may be present within a cell, present in the cellular medium, or prepared in various forms, such as lysates or isolated preparations. As such, in some embodiments, the recombinant lipase polypeptides can be an isolated polypeptide.

The terms “isolated” and “purified” are used to refer to a molecule (e.g., an isolated nucleic acid, polypeptide, etc.) or other component that is removed from at least one other component with which it is naturally associated. The term “purified” does not require absolute purity, rather it is intended as a relative definition.

As used herein, “substantially pure polypeptide” refers to a composition in which the polypeptide species is the predominant species present (i.e., on a molar or weight basis it is more abundant than any other individual macromolecular species in the composition), and is generally a substantially purified composition when the object species comprises at least about 50 percent of the macromolecular species present by mole or % weight. Generally, a substantially pure lipase composition comprises about 60% or more, about 70% or more, about 80% or more, about 90% or more, about 95% or more, and about 98% or more of all macromolecular species by mole or % weight present in the composition. In some embodiments, the object species is purified from a starting preparation to essential homogeneity (i.e., contaminant species cannot be detected in the composition by conventional detection methods) wherein the composition consists essentially of a single macromolecular species. Solvent species, small molecules (<500 Daltons), and elemental ion species are not considered macromolecular species. In some embodiments, the isolated recombinant lipase polypeptides are substantially pure polypeptide compositions. In some embodiments, the isolated recombinant lipase polypeptides are substantially pure polypeptide compositions. In some embodiments, substantially pure recombinant lipase polypeptide preparations added to formulations suitable for use in the present invention (e.g., polysaccharides, surfactants, etc.).

As used herein, “increased enzymatic activity” or “enhanced catalytic activity” refers to an improved property of the engineered lipase polypeptide that can be represented by an increase in specific activity (e.g., product produced/time/weight protein) or an increase in percent conversion of the substrate to the product (e.g., percent conversion of starting amount of substrate to product in a specified time period using a specified amount of lipase) as compared to the reference lipase enzyme. Exemplary methods to determine enzyme activity are provided in the Examples. Any property relating to enzyme activity may be affected, including the classical enzyme properties of K_(m), V_(max) or k_(cat), changes of which can lead to increased enzymatic activity. Improvements in enzyme activity can be from about 1.1 fold the enzymatic activity of the corresponding wild-type enzyme, to as much as 2-fold, 5-fold, 10-fold, 20-fold, 25-fold, 50-fold, 75-fold, 100-fold, 150-fold, 200-fold or more enzymatic activity than the naturally occurring lipase or another engineered lipase from which the lipase polypeptides were derived.

Lipase activity can be measured by any suitable method known in the art (e.g., standard assays, such as monitoring changes in spectrophotometric properties of reactants or products). In some embodiments, the amount of products produced can be measured by High-Performance Liquid Chromatography (HPLC) separation combined with UV absorbance In some embodiments, the amount of products produced can be measured using a RAPIDFIRE® mass spectrometer, while in some other embodiments, the products can be measured using alternative methods known in the art. Comparisons of enzyme activities are made using a defined preparation of enzyme, a defined assay under a set condition, and one or more defined substrates, as further described in detail herein.

It is not intended that the term be limited to the use of any particular protease to assess the stability of a protein. Indeed, the engineered lipases of the present invention are stable and retain enzymatic activity in the presence of or following exposure to various proteases. In some embodiments, the engineered lipases are stable in the presence of trypsin, chymotrypsin, and/or pepsin. However, it is not intended that the present invention be limited to any specific protease or any particular method of assessing proteolytic stability.

As used herein, the term “pH stability” refers to the ability of a protein (e.g., a recombinant lipase of the present invention) to function after incubation at a particular pH. In some embodiments, the present invention provides recombinant lipases that are stable at a range of pHs, including, but not limited to the range of pH 2 to pH 7. In some embodiments, the recombinant lipases are stable at different pH ranges, as indicated in the Examples provided herein. It is not intended that the present invention be limited to any pH stability level nor pH range.

As used herein, the term “improved tolerance to acidic pH” means that a recombinant lipase according to the invention will have increased stability (higher retained activity at about pH 7, 6, 5, 4 3, 2, or even lower, after exposure to acidic pH for a specified period of time [e.g., 1 hour, up to 24 hours, etc.]) as compared to a reference lipase or another enzyme.

“Physiological pH” as used herein means the pH range generally found in a subject's (e.g., human) blood (e.g., pH 7.2-7.4).

The term “basic pH” (e.g., used with reference to improved stability to basic pH conditions or increased tolerance to basic pH) means a pH range of about 7 to 11, or in some embodiments, greater than pH 11.

The term “acidic pH” (e.g., used with reference to improved stability to acidic pH conditions or increased tolerance to acidic pH) means a pH range that encompasses any pH values less than 7. In some embodiments, the acid pH is less than 7, while in some other embodiments, the pH is less than about 6, 5, 4, 3, 2, or lower. In some alternative embodiments, the recombinant lipases of the present invention are stable at pH levels of 2 to 4. However, it is not intended that the present invention be limited to any specific pH value or range of values.

As used herein, the phrase “gastric challenge” refers to the exposure of the recombinant lipases of the present invention to a low pH environment and the presence of at least one enzyme (e.g., pepsin), such that the recombinant lipase is exposed to conditions that may be encountered in the stomach (e.g., the human stomach).

As used herein, the phrase “multiple challenges in sequence” refers to the exposure of the recombinant lipases of the present invention to a series of challenge conditions. For example, in some embodiments, a one hour heat challenge was followed by a one hour gastric challenge, and then followed by a one hour intestinal challenge. It is not intended that the present invention be limited to any specific challenges and/or challenge conditions or a specific sequence of challenges.

The terms “thermal stability” and “thermostability” refer to the ability of a protein (e.g., a recombinant lipase of the present invention) to function at a particular temperature. In some embodiments, the term refers to the ability of a protein to function following incubation at a particular temperature. In some embodiments, the recombinant lipases of the present invention are “thermotolerant” (i.e., the enzymes maintain their catalytic activity at elevated temperatures). In some embodiments, the recombinant lipases resist inactivation at elevated temperatures, and in some additional embodiments, maintain catalytic activity at elevated temperatures for prolonged exposure times. These terms are used interchangeably herein. It is not intended that the present invention be limited to any specific temperature and/or exposure time. Such stability can be measured by any method known in the art (e.g., the methods described herein). It is not intended that the present invention be limited to any specific temperature stability level nor temperature range. In some embodiments, thermal stability is measured following incubation of a protein (e.g., a recombinant lipase of the present invention) at a particular temperature.

The term “chemical stability” refers to the ability of a protein (e.g., a recombinant lipase of the present invention) to function in the presence of a chemical that adversely affects the function of another protein. It is not intended that the present invention be limited to any specific chemical stability level nor range of chemical stabilities.

“Conversion” refers to the enzymatic conversion (or biotransformation) of a substrate(s) to the corresponding product(s). “Percent conversion” refers to the percent of the substrate that is converted to the product within a period of time under specified conditions. Thus, the “enzymatic activity” or “activity” of a lipase polypeptide can be expressed as “percent conversion” of the substrate to the product in a specific period of time.

As used herein, “hybridization stringency” relates to hybridization conditions, such as washing conditions, in the hybridization of nucleic acids. Generally, hybridization reactions are performed under conditions of lower stringency, followed by washes of varying but higher stringency. The term “moderately stringent hybridization” refers to conditions that permit target-DNA to bind a complementary nucleic acid that has about 60% identity, preferably about 75% identity, about 85% identity to the target DNA, with greater than about 90% identity to target-polynucleotide. Exemplary moderately stringent conditions are conditions equivalent to hybridization in 50% formamide, 5× Denhart's solution, 5×SSPE, 0.2% SDS at 42° C., followed by washing in 0.2×SSPE, 0.2% SDS, at 42° C. “High stringency hybridization” refers generally to conditions that are about 10° C. or less from the thermal melting temperature T_(m) as determined under the solution condition for a defined polynucleotide sequence. In some embodiments, a high stringency condition refers to conditions that permit hybridization of only those nucleic acid sequences that form stable hybrids in 0.018M NaCl at 65° C. (i.e., if a hybrid is not stable in 0.018M NaCl at 65° C., it will not be stable under high stringency conditions, as contemplated herein). High stringency conditions can be provided, for example, by hybridization in conditions equivalent to 50% formamide, 5× Denhart's solution, 5×SSPE, 0.2% SDS at 42° C., followed by washing in 0.1×SSPE, and 0.1% SDS at 65° C. Another high stringency condition is hybridizing in conditions equivalent to hybridizing in 5×SSC containing 0.1% (w/v) SDS at 65° C. and washing in 0.1×SSC containing 0.1% SDS at 65° C. Other high stringency hybridization conditions, as well as moderately stringent conditions, are described in the references cited above.

As used herein, “codon optimized” refers to changes in the codons of the polynucleotide encoding a protein to those preferentially used in a particular organism such that the encoded protein is more efficiently expressed in the organism of interest. Although the genetic code is degenerate in that most amino acids are represented by several codons, called “synonyms” or “synonymous” codons, it is well known that codon usage by particular organisms is nonrandom and biased towards particular codon triplets. This codon usage bias may be higher in reference to a given gene, genes of common function or ancestral origin, highly expressed proteins versus low copy number proteins, and the aggregate protein coding regions of an organism's genome. In some embodiments, the polynucleotides encoding the lipase enzymes may be codon optimized for optimal production from the host organism selected for expression.

As used herein, “control sequence” refers herein to all components that are necessary or advantageous for the expression of a polynucleotide and/or polypeptide of the present application.

At a minimum, the control sequences include a promoter, and transcriptional and translational stop signals. The control sequences may be provided with linkers for the purpose of introducing specific restriction sites facilitating ligation of the control sequences with the coding region of the nucleic acid sequence encoding a polypeptide.

“Operably linked” is defined herein as a configuration in which a control sequence is appropriately placed (i.e., in a functional relationship) at a position relative to a polynucleotide of interest such that the control sequence directs or regulates the expression of the polynucleotide and/or polypeptide of interest.

Polynucleotides Encoding Engineered Lipase Polypeptides, Expression Vectors and Host Cells:

The present invention provides polynucleotides encoding the engineered lipase polypeptides described herein. In some embodiments, the polynucleotides are operatively linked to one or more heterologous regulatory sequences that control gene expression to create a recombinant polynucleotide capable of expressing the polypeptide. Expression constructs containing a heterologous polynucleotide encoding the engineered lipase polypeptides can be introduced into appropriate host cells to express the corresponding lipase polypeptide.

As will be apparent to the skilled artisan, availability of a protein sequence and the knowledge of the codons corresponding to the various amino acids provide a description of all the polynucleotides capable of encoding the subject polypeptides. The degeneracy of the genetic code, where the same amino acids are encoded by alternative or synonymous codons, allows an extremely large number of nucleic acids to be made, all of which encode the engineered lipase polypeptide. Thus, having knowledge of a particular amino acid sequence, those skilled in the art could make any number of different nucleic acids by simply modifying the sequence of one or more codons in a way which does not change the amino acid sequence of the protein. In this regard, the present invention specifically contemplates each and every possible variation of polynucleotides that could be made encoding the polypeptides described herein by selecting combinations based on the possible codon choices, and all such variations are to be considered specifically disclosed for any polypeptide described herein, including the variants provided in Tables 4-1, 4-2, 4-3, 4-4, 4-5, 4-6, 4-7, and 5-1.

In various embodiments, the codons are preferably selected to fit the host cell in which the protein is being produced. For example, preferred codons used in bacteria are used for expression in bacteria, while preferred codons used in fungi are used for expression in fungi. Consequently, codon optimized polynucleotides encoding the engineered lipase polypeptides contain preferred codons at about 40%, 50%, 60%, 70%, 80%, or greater than 90% of codon positions of the full length coding region.

In some embodiments, the present invention provides a recombinant polynucleotide sequence having at least about 85%, about 86%, about 87%, about 88%, about 89%, about 90%, about 91%, about 92%, about 93%, about 94%, about 95%, about 96%, about 97%, about 98%, about 99%, or more sequence identity to SEQ ID NO: 1, 93, 349, 441, 539, 645, 757, and/or 867.

In some embodiments, an isolated polynucleotide encoding any of the engineered lipase polypeptides provided herein is manipulated in a variety of ways to provide for expression of the gene and production of the polypeptide. In some embodiments, the polynucleotides encoding the polypeptides are provided as expression vectors, in which one or more control sequences is present to regulate the expression of the polynucleotides and/or polypeptides. Manipulation of the isolated polynucleotide prior to its insertion into a vector may be desirable or necessary depending on the expression vector. The techniques for modifying polynucleotides and nucleic acid sequences utilizing recombinant DNA methods are well known in the art.

In some embodiments, the control sequences include among other sequences, promoters, leader sequences, polyadenylation sequences, propeptide sequences, signal peptide sequences, and transcription terminators. As known in the art, suitable control sequences can be selected based on the host cells used. It is not intended that the present invention be limited to any specific control sequences.

Exemplary promoters for bacterial host cells include, but are not limited to promoters obtained from the genes for Escherichia coli lactose operon, tryptophan operon, arabinose operon, T7 promoter from the T7 bacteriophage, and Saccharopolyspora erythraea erythromycin resistance gene.

Exemplary promoters for filamentous fungal host cells, include promoters obtained from the genes for Aspergillus oryzae TAKA amylase, Rhizomucor miehei aspartic proteinase, Aspergillus niger neutral alpha-amylase, Aspergillus niger acid stable alpha-amylase, Aspergillus niger or Aspergillus awamori glucoamylase, Rhizomucor miehei lipase, Aspergillus oryzae alkaline protease, Aspergillus oryzae triose phosphate isomerase, Aspergillus nidulans acetamidase, and Fusarium oxysporum trypsin-like protease (See e.g., WO 96/00787), as well as the NA2-tpi promoter (a hybrid of the promoters from the genes for Aspergillus niger neutral alpha-amylase and Aspergillus oryzae triose phosphate isomerase), and mutant, truncated, and hybrid promoters thereof. Exemplary yeast cell promoters can be from the genes can be from the genes for Saccharomyces cerevisiae enolase (ENO-1), Saccharomyces cerevisiae galactokinase (GAL1), Saccharomyces cerevisiae alcohol dehydrogenase/glyceraldehyde-3-phosphate dehydrogenase (ADH2/GAP), and Saccharomyces cerevisiae 3-phosphoglycerate kinase. Other useful promoters for yeast host cells are known in the art (See e.g., Romanos et al., Yeast 8:423-488 [1992]).

Exemplary promoters for use in mammalian cells include, but are not limited to those from cytomegalovirus (CMV), Simian vacuolating virus 40 (SV40), from Homo sapiens phosphoglycerate kinase, beta actin, elongation factor-1a or glyceraldehyde-3-phosphate dehydrogenase, or from Gallus gallus β-actin.

In some embodiments, the control sequence is a suitable transcription terminator sequence, a sequence recognized by a host cell to terminate transcription. The terminator sequence is operably linked to the 3′ terminus of the nucleic acid sequence encoding the polypeptide. Any terminator which is functional in the host cell of choice finds use in the present invention. For example, exemplary transcription terminators for bacterial host cells can be obtained from the T7 bacterial phage for the T7 terminator, or Escherichia coli ribosomal RNA, for example the rrnB terminator. For example, exemplary transcription terminators for filamentous fungal host cells can be obtained from the genes for Aspergillus oryzae TAKA amylase, Aspergillus niger glucoamylase, Aspergillus nidulans anthranilate synthase, Aspergillus niger alpha-glucosidase, and Fusarium oxysporum trypsin-like protease. Exemplary terminators for yeast host cells can be obtained from the genes for Saccharomyces cerevisiae enolase, Saccharomyces cerevisiae cytochrome C (CYC1), and Saccharomyces cerevisiae glyceraldehyde-3-phosphate dehydrogenase. Other useful terminators for yeast host cells are known in the art (See e.g., Romanos et al., supra). Exemplary terminators for mammalian cells include, but are not limited to those from cytomegalovirus (CMV), Simian vacuolating virus 40 (SV40), or from Homo sapiens growth hormone.

In some embodiments, the control sequence is a suitable leader sequence, a non-translated region of an mRNA that is important for translation by the host cell. The leader sequence is operably linked to the 5′ terminus of the nucleic acid sequence encoding the polypeptide. Any leader sequence that is functional in the host cell of choice may be used. Exemplary leaders for filamentous fungal host cells are obtained from the genes for Aspergillus oryzae TAKA amylase and Aspergillus nidulans triose phosphate isomerase. Suitable leaders for yeast host cells include, but are not limited to those obtained from the genes for Saccharomyces cerevisiae enolase (ENO-1), Saccharomyces cerevisiae 3-phosphoglycerate kinase, Saccharomyces cerevisiae alpha-factor, and Saccharomyces cerevisiae alcohol dehydrogenase/glyceraldehyde-3-phosphate dehydrogenase (ADH2/GAP).

In some embodiments, the control sequence may also be a polyadenylation sequence, a sequence operably linked to the 3′ terminus of the nucleic acid sequence and which, when transcribed, is recognized by the host cell as a signal to add polyadenosine residues to transcribed mRNA. Any polyadenylation sequence which is functional in the host cell of choice may be used in the present invention. Exemplary polyadenylation sequences for filamentous fungal host cells include, but are not limited to those from the genes for Aspergillus oryzae TAKA amylase, Aspergillus niger glucoamylase, Aspergillus nidulans anthranilate synthase, Fusarium oxysporum trypsin-like protease, and Aspergillus niger alpha-glucosidase. Useful polyadenylation sequences for yeast host cells are also known in the art (See e.g., Guo and Sherman, Mol. Cell. Biol., 15:5983-5990 [1995]).

In some embodiments, the control sequence is a signal peptide coding region that codes for an amino acid sequence linked to the amino terminus of a polypeptide and directs the encoded polypeptide into the cell's secretory pathway. The 5′ end of the coding sequence of the nucleic acid sequence may inherently contain a signal peptide coding region naturally linked in translation reading frame with the segment of the coding region that encodes the secreted polypeptide. Alternatively, the 5′ end of the coding sequence may contain a signal peptide coding region that is foreign to the coding sequence.

Any signal peptide coding region that directs the expressed polypeptide into the secretory pathway of a host cell of choice finds use for expression of the engineered lipase polypeptides provided herein. Effective signal peptide coding regions for filamentous fungal host cells include, but are not limited to the signal peptide coding regions obtained from the genes for Aspergillus oryzae TAKA amylase, Aspergillus niger neutral amylase, Aspergillus niger glucoamylase, Rhizomucor miehei aspartic proteinase, Humicola insolens cellulase, and Humicola lanuginosa lipase. Useful signal peptides for yeast host cells include, but are not limited to those from the genes for Saccharomyces cerevisiae alpha-factor and Saccharomyces cerevisiae invertase. Useful signal peptides for mammalian host cells include but are not limited to those from the genes for immunoglobulin gamma (IgG).

In some embodiments, the control sequence is a propeptide coding region that codes for an amino acid sequence positioned at the amino terminus of a polypeptide. The resultant polypeptide is referred to as a “proenzyme,” “propolypeptide,” or “zymogen,” in some cases). A propolypeptide can be converted to a mature active polypeptide by catalytic or autocatalytic cleavage of the propeptide from the propolypeptide.

In another aspect, the present invention also provides a recombinant expression vector comprising a polynucleotide encoding an engineered lipase polypeptide, and one or more expression regulating regions such as a promoter and a terminator, a replication origin, etc., depending on the type of hosts into which they are to be introduced. in some embodiments, the various nucleic acid and control sequences described above are joined together to produce a recombinant expression vector which includes one or more convenient restriction sites to allow for insertion or substitution of the nucleic acid sequence encoding the variant lipase polypeptide at such sites. Alternatively, the polynucleotide sequence(s) of the present invention are expressed by inserting the polynucleotide sequence or a nucleic acid construct comprising the polynucleotide sequence into an appropriate vector for expression. In creating the expression vector, the coding sequence is located in the vector so that the coding sequence is operably linked with the appropriate control sequences for expression.

The recombinant expression vector may be any vector (e.g., a plasmid or virus), that can be conveniently subjected to recombinant DNA procedures and can result in the expression of the variant lipase polynucleotide sequence. The choice of the vector will typically depend on the compatibility of the vector with the host cell into which the vector is to be introduced. The vectors may be linear or closed circular plasmids.

In some embodiments, the expression vector is an autonomously replicating vector (i.e., a vector that exists as an extra-chromosomal entity, the replication of which is independent of chromosomal replication, such as a plasmid, an extra-chromosomal element, a minichromosome, or an artificial chromosome). The vector may contain any means for assuring self-replication. In some alternative embodiments, the vector may be one which, when introduced into the host cell, is integrated into the genome and replicated together with the chromosome(s) into which it has been integrated. Furthermore, a single vector or plasmid or two or more vectors or plasmids which together contain the total DNA to be introduced into the genome of the host cell, or a transposon may be used.

In some embodiments, the expression vector preferably contains one or more selectable markers, which permit easy selection of transformed cells. A “selectable marker” is a gene the product of which provides for biocide or viral resistance, resistance to heavy metals, prototrophy to auxotrophs, and the like. Suitable markers for bacterial host cells include, but are not limited to carbenicillin, ampicillin, chloramphenicol, tetracycline, kanamycin and zeocin. Suitable markers for yeast host cells include, but are not limited to ADE2, HIS3, LEU2, LYS2, MET3, TRP1, and URA3. Selectable markers for use in a filamentous fungal host cell include, but are not limited to, amdS (acetamidase), argB (ornithine carbamoyltransferases), bar (phosphinothricin acetyltransferase), hph (hygromycin phosphotransferase), niaD (nitrate reductase), pyrG (orotidine-5′-phosphate decarboxylase), sC (sulfate adenyltransferase), and trpC (anthranilate synthase), as well as equivalents thereof. In another aspect, the present invention provides a host cell comprising a polynucleotide encoding at least one engineered lipase polypeptide of the present application, the polynucleotide being operatively linked to one or more control sequences for expression of the engineered lipase enzyme(s) in the host cell.

Host cells for use in expressing the polypeptides encoded by the expression vectors of the present invention are well known in the art and include but are not limited to, bacterial cells (e.g., E. coli); fungal cells, such as yeast cells (e.g., Saccharomyces cerevisiae and Pichia pastoris [e.g., ATCC Accession No. 201178]); insect cells (e.g., Drosophila S2 and Spodoptera Sf9 cells), plant cells, animal cells (e.g., CHO, COS, and BHK), and human cells (e.g., HEK293T, human fibroblast, THP-1, Jurkat and Bowes melanoma cell lines).

Accordingly, in another aspect, the present invention provides methods for producing the engineered lipase polypeptides, where the methods comprise culturing a host cell capable of expressing a polynucleotide encoding the engineered lipase polypeptide under conditions suitable for expression of the polypeptide. In some embodiments, the methods further comprise the steps of isolating and/or purifying the lipase polypeptides, as described herein.

Appropriate culture media and growth conditions for the above-described host cells are well known in the art. Polynucleotides for expression of the lipase may be introduced into cells by various methods known in the art. Techniques include, among others, electroporation, biolistic particle bombardment, liposome mediated transfection, calcium chloride transfection, and protoplast fusion.

The engineered lipase with the properties disclosed herein can be obtained by subjecting the polynucleotide encoding the naturally occurring or engineered lipase polypeptide to mutagenesis and/or directed evolution methods known in the art, and as described herein. An exemplary directed evolution technique is mutagenesis and/or DNA shuffling (See e.g., Stemmer, Proc. Natl. Acad. Sci. USA 91:10747-10751 [1994]; WO 95/22625; WO 97/0078; WO 97/35966; WO 98/27230; WO 00/42651; WO 01/75767 and U.S. Pat. 6,537,746). Other directed evolution procedures that can be used include, among others, staggered extension process (StEP), in vitro recombination (See e.g., Zhao et al., Nat. Biotechnol., 16:258-261 [1998]), mutagenic PCR (See e.g., Caldwell et al., PCR Methods Appl., 3:S136-S140 [1994]), and cassette mutagenesis (See e.g., Black et al., Proc. Natl. Acad. Sci. USA 93:3525-3529 [1996]).

Recombinant polypeptides can be produced using any suitable methods known in the art. Genes encoding the wild-type polypeptide of interest can be cloned in vectors, such as plasmids, and expressed in desired hosts, such as E. coli, etc. Variants of recombinant polypeptides can be generated by various methods known in the art. Indeed, there is a wide variety of different mutagenesis techniques well known to those skilled in the art. In addition, mutagenesis kits are also available from many commercial molecular biology suppliers. Methods are available to make specific substitutions at defined amino acids (site-directed), specific or random mutations in a localized region of the gene (regio-specific), or random mutagenesis over the entire gene (e.g., saturation mutagenesis). Numerous suitable methods are known to those in the art to generate enzyme variants, including but not limited to site-directed mutagenesis of single-stranded DNA or double-stranded DNA using PCR, cassette mutagenesis, gene synthesis, error-prone PCR, shuffling, and chemical saturation mutagenesis, or any other suitable method known in the art. Mutagenesis and directed evolution methods can be readily applied to enzyme-encoding polynucleotides to generate variant libraries that can be expressed, screened, and assayed. Any suitable mutagenesis and directed evolution methods find use in the present invention and are well known in the art (See e.g., U.S. Pat. Nos. 5,605,793, 5,811,238, 5,830,721, 5,834,252, 5,837,458, 5,928,905, 6,096,548, 6,117,679, 6,132,970, 6,165,793, 6,180,406, 6,251,674, 6,265,201, 6,277,638, 6,287,861, 6,287,862, 6,291,242, 6,297,053, 6,303,344, 6,309,883, 6,319,713, 6,319,714, 6,323,030, 6,326,204, 6,335,160, 6,335,198, 6,344,356, 6,352,859, 6,355,484, 6,358,740, 6,358,742, 6,365,377, 6,365,408, 6,368,861, 6,372,497, 6,337,186, 6,376,246, 6,379,964, 6,387,702, 6,391,552, 6,391,640, 6,395,547, 6,406,855, 6,406,910, 6,413,745, 6,413,774, 6,420,175, 6,423,542, 6,426,224, 6,436,675, 6,444,468, 6,455,253, 6,479,652, 6,482,647, 6,483,011, 6,484,105, 6,489,146, 6,500,617, 6,500,639, 6,506,602, 6,506,603, 6,518,065, 6,519,065, 6,521,453, 6,528,311, 6,537,746, 6,573,098, 6,576,467, 6,579,678, 6,586,182, 6,602,986, 6,605,430, 6,613,514, 6,653,072, 6,686,515, 6,703,240, 6,716,631, 6,825,001, 6,902,922, 6,917,882, 6,946,296, 6,961,664, 6,995,017, 7,024,312, 7,058,515, 7,105,297, 7,148,054, 7,220,566, 7,288,375, 7,384,387, 7,421,347, 7,430,477, 7,462,469, 7,534,564, 7,620,500, 7,620,502, 7,629,170, 7,702,464, 7,747,391, 7,747,393, 7,751,986, 7,776,598, 7,783,428, 7,795,030, 7,853,410, 7,868,138, 7,783,428, 7,873,477, 7,873,499, 7,904,249, 7,957,912, 7,981,614, 8,014,961, 8,029,988, 8,048,674, 8,058,001, 8,076,138, 8,108,150, 8,170,806, 8,224,580, 8,377,681, 8,383,346, 8,457,903, 8,504,498, 8,589,085, 8,762,066, 8,768,871, 8,849,575, 9,593,326, 9,665,694, 9,684,771, 9,803,224, 9,864,833, 9.821,613, 9,996,661, 10,738,286, and all related US, as well as PCT and non-US counterparts; Ling et al., Anal.

In some embodiments, the enzyme variants obtained following mutagenesis treatment are screened by subjecting the enzyme variants to a defined temperature (or other assay conditions) and measuring the amount of enzyme activity remaining after heat treatments or other assay conditions. DNA containing the polynucleotide encoding the lipase polypeptide is then isolated from the host cell, sequenced to identify the nucleotide sequence changes (if any), and used to express the enzyme in a different or the same host cell. Measuring enzyme activity from the expression libraries can be performed using any suitable method known in the art (e.g., standard biochemistry techniques, such as HPLC analysis).

For engineered polypeptides of known sequence, the polynucleotides encoding the enzyme can be prepared by standard solid-phase methods, according to known synthetic methods. In some embodiments, fragments of up to about 100 bases can be individually synthesized, then joined (e.g., by enzymatic or chemical ligation methods, or polymerase mediated methods) to form any desired continuous sequence. For example, polynucleotides and oligonucleotides disclosed herein can be prepared by chemical synthesis using the classical phosphoramidite method (See e.g., Beaucage et al., Tetra. Lett., 22:1859-69 [1981]; and Matthes et al., EMBO J., 3:801-05 [1984]), as it is typically practiced in automated synthetic methods. According to the phosphoramidite method, oligonucleotides are synthesized (e.g., in an automatic DNA synthesizer), purified, annealed, ligated and cloned in appropriate vectors. However, it is not intended that the present invention be limited to any specific method for production of polynucleotides and oligonucleotides, as any suitable method finds use in the present invention.

Accordingly, in some embodiments, a method for preparing the engineered lipase polypeptide can comprise: (a) synthesizing a polynucleotide encoding a polypeptide comprising an amino acid sequence selected from the amino acid sequence of any variant provided in Table 4-1, 4-2, 4-3, 4-4, 4-5, 4-6, 4-7, and/or 5-1, as well as SEQ ID NOS: 2, 94, 350, 442, 540, 646, 758, and/or 868, and (b) expressing the lipase polypeptide encoded by the polynucleotide. In some embodiments of the method, the amino acid sequence encoded by the polynucleotide comprises one or several (e.g., up to 3, 4, 5, or up to 10) amino acid residue deletions, insertions and/or substitutions. In some embodiments, the amino acid sequence comprises 1-2, 1-3, 1-4, 1-5, 1-6, 1-7, 1-8, 1-9, 1-10, 1-15, 1-20, 1-21, 1-22, 1-23, 1-24, 1-25, 1-30, 1-35, 1-40, 1-45, or 1-50 amino acid residue deletions, insertions and/or substitutions. In some embodiments, the amino acid sequence comprises 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, or 50 amino acid residue deletions, insertions and/or substitutions. In some embodiments, the amino acid sequence comprises 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 18, 20, 21, 22, 23, 24, or 25 amino acid residue deletions, insertions and/or substitutions. In some embodiments, the substitutions comprise conservative and/or non-conservative substitutions.

The expressed engineered lipase polypeptide can be assessed for any desired improved property (e.g., activity, selectivity, stability, acid tolerance, protease sensitivity, etc.), using any suitable assay known in the art, including but not limited to the assays and conditions described herein.

In some embodiments, any of the engineered lipase polypeptides expressed in a host cell are recovered from the cells and/or the culture medium using any one or more of the well-known techniques for protein purification, including, among others, lysozyme treatment, sonication, filtration, salting-out, heat treatment, ultra-centrifugation, and chromatography.

Chromatographic techniques for isolation of the lipase polypeptides include, among others, reverse phase chromatography high performance liquid chromatography, ion exchange chromatography, hydrophobic interaction chromatography, gel electrophoresis, and affinity chromatography. Conditions for purifying a particular enzyme depends, in part, on factors such as net charge, hydrophobicity, hydrophilicity, molecular weight, molecular shape, etc., and will be apparent to those having skill in the art. In some embodiments, affinity techniques may be used to isolate the improved variant lipase enzymes. In some embodiments utilizing affinity chromatography purification, any antibody which specifically binds the variant lipase polypeptide finds use.

In some embodiments utilizing affinity chromatography purification, proteins that bind to the glycans covalently attached to lipase find use. In still other embodiments utilizing affinity-chromatography purifications, any small molecule that binds to the lipase active site finds use. For the production of antibodies, various host animals, including but not limited to rabbits, mice, rats, etc., are immunized by injection with a polypeptide (e.g., a lipase variant), or a fragment thereof.

EXAMPLE 3 High-Throughput (HTP) Growth of Lipase Variants and Screening Conditions

Experiments conducted on the growth and screening of lipase variants are described below.

High-Throughput (HTP) Growth of B. thermoamylovorans Lipase (btLIP) and Lipase (LIP) Variants:

Transformed E. coli cells were selected by plating onto LB agar plates containing 1% glucose with selection. After overnight incubation at 37° C., colonies were placed into the wells of 96-well shallow flat bottom plates (NUNC™, Thermo-Scientific) filled with 180 μl/well LB supplemented with 1% glucose and selection. The cultures were allowed to grow overnight for 18-20 hours in a shaker incubator (200 rpm, 30° C., and 85% relative humidity; Kuhner). Overnight growth samples (20 μL) were transferred into COSTAR® 96-well deep plates filled with 380 μL of Terrific Broth supplemented with a selection compound (e.g., chloramphenicol). The plates were incubated for 135 minutes in a shaker incubator (250 rpm, 30° C., and 85% relative humidity; Kuhner). The expression of the lipase variants was then induced with 40 μL of 10 mM IPTG in sterile water and the cultures incubated overnight for 20-24 hours in a shaker incubator (250 rpm, 30° C., and 85% relative humidity; Kuhner). The cells were pelleted by centrifugation (4000 rpm×20 min), the supernatants were discarded, and the cells were frozen at −80° C. prior to analysis.

Lysis of HTP Pellets:

First, 200-400 μL of lysis buffer (1× PBS, 1 mg/ml lysozyme, and 0.5 mg/ml polymyxin B sulfate) were added to the cell pellets. The cell pellet and buffer were gently shaken for 1.5-2 h at room temperature, and centrifuged (4000 rpm×5 min) prior to use of the clarified lysates in the various HTP assays described herein. Analysis of these lysates by SDS-PAGE revealed the presence of an overexpressed protein at an apparent MW of ˜45 kDa, consistent with the expected MW of btLIP.

Analysis of Clarified Lysates for Lipase Activity:

The btLIP variant activity was determined by measuring the formation of oleic acid, diolein, and monoolein, by their change in abundance over time. For this assay, 90 μL of 100 mM sodium phosphate and 2.5 μL triolein pH 7.0, were mixed with 10 μL of lysate and added to the wells of a poly-acrylate 96-well microtiter plate (COSTAR® plate #3635, Corning) and incubated at 37° C. for 30 min to 1 hr. Reactions were quenched with 600 μL ACN:IPA (1:3), clarified with centrifugation and separated on a C18 POROSHELL® 5 μm 150 mm column run with an isocratic flow of 55% IPA in acetonitrile to detect oleic acid, diolein, monoolein, and triolein at 214 nm. Alternatively, quenched reactions were clarified and diluted 10 μL into 190 μL 50:50 IPA:MeOH, shaken for 1 min, then diluted once again by adding 10 μL into 190 μL of 50:25:25 H₂O:IPA:MeOH. Samples were then analyzed by RAPIDFIRE® MS. In the following Examples, “unchallenged activity” refers to the lipase activity determinations conducted without any external pretreatment/challenges as described in the following assay method descriptions.

EXAMPLE 6 Validation of a Surgical Model of Exocrine Pancreatic Insufficiency in Miniature Swine

A surgical model of exocrine pancreatic insufficiency (EPI) was produced in miniature swine by pancreatic duct ligation. Starting 7 days prior to surgery and continuing throughout the experiment, female SINCLAIR™ miniature swine, aged 3-4 months, were fed a High Fat Diet (HFD; Sinclair Standard diet S-9 mixed 10:1, w/w, with BERTOLLI® olive oil) once a day. Total fecal output over 24 hours was collected on 3 consecutive days prior to surgery, and on days 15, 16, and 17 post surgery. The daily total fecal collections from each animal were prepared for subsequent analytics by adding a volume of distilled water at approximately 1.5× the fecal net weight, homogenizing, dividing into 3×50 mL aliquots, and freezing at −20° C. until analysis. The model was validated by measuring the coefficient of fat absorption (CFA; by modified Van de Kamer method; See, Van de Kamer, in Seligson (ed), Standard Methods of Clinical Chemistry, volume 2, Academic Press, New York, N.Y. [1958], pp. 34-39), and coefficient of nitrogen absorption (CNA; Kjeldahl total nitrogen by Vario Max CN machine by combustion method; See, Watson et al., in Peters et al. (eds.) Recommended Methods of Manure Analysis, Univ. of Wisconsin Cooperative Extension Publishing, Publication No. A3769. Madison, Wis. [2003], p. 18-24) in fecal samples, and assessing the percent change before and after surgery. Prior to surgery, healthy miniature swine CFA and CNA was 91.3%±1.1 SEM and 84.2%±1.2 SEM, respectively. After surgery CFA decreased by 53.2% (p<0.0001, n=11) and CNA decreased by 28.7% (p<0.0001, n=11), thus validating this surgical model for EPI studies.

EXAMPLE 7 In Vivo Characterization of SEQ ID NO: 868, Compared to CREON® Pancrelipase

Validated SINCLAIR™ miniature swine surgical models of EPI (female, aged 4-5 months) were carried forward into in vivo studies to evaluate an engineered lipase variant (SEQ ID NO: 868) compared to the current standard of care (CREON® pancrelipase; AbbVie, Inc.). Starting at least 8 days prior to dosing, animals were offered HFD (Sinclair Standard S-9 diet mixed 10:1, w/w, with BERTOLLI® brand olive oil) combined with one 3.9 oz. cup of unsweetened applesauce once a day. During dosing days, the meal was prepared for each animal sequentially to ensure minimal ex vivo lipase interaction with dietary fats prior to ingestion. In brief, HFD was prepared first in a clean feed bowl. Next, enzyme (0.5 g lyophilized SEQ ID NO: 868 powder or 5.6 g of microspheres pooled from 7×36,000 U CREON® pancrelipase capsules, which corresponded to 258,000 U and 252,000 U of lipase, respectively) was mixed into a 3.9 oz. cup of unsweetened applesauce, as the acidic pH protected against early enzyme activation. Units of enzyme dosed per meal was based upon specific activity of lipase, determined by the USP lipase assay (United States Pharmacopeia and National Formulary (USP 42-NF 37). Rockville, Md.: United Stales Pharmacopeia Convention; 2016; available at online.uspnf.com/uspnf/document/GUID-AC788D41-90A2-4F36-A6E7-769954A9ED09_1_en-US), and total calculated fat provided in the meal. The lipase-applesauce mixture was then transferred to the HFD and quickly mixed. Finally, the feed bowl was immediately offered to the animals before moving on to the next preparation. After 2 hours, the feed bowl was removed; the animals having consumed the entire meal within 30 minutes or less. A crossover design was used to maximize the number of miniature swine per group (n=3). The study incorporated an 8 day ‘washout’ (once daily HFD+applesauce without enzyme) between each 10-day dosing phase. Total fecal matter was collected 3 consecutive days immediately prior to dosing start and 24 hours post dosing on days 9, 10, and 11 of each phase. Fecal samples were prepared by adding a volume of distilled water at approximately 1.5× the fecal net weight to each daily total fecal collection, homogenizing, dividing into 3×50 mL and freezing at −20° C. until analysis, discarding the rest. Analytics were completed as described for model validation above. Both CREON® pancrelipase and SEQ ID NO: 868 resulted in a similar improvement in CFA to a value not significantly different than pre-surgical baseline.

EXAMPLE 8 In Vivo Dose Response Characterization of SEQ ID NO: 868

Validated SINCLAIR™ miniature swine surgical models of EPI (female, aged 4-6 months) were utilized for additional in vivo SEQ ID NO: 868 dose response studies. The HFD and feeding regimen, lipase mixing protocol, fecal sample collection and preparation, and analytics were the same as described above. Compared to pre-surgical values (92.8%+/−3.2 SD, n=8), post-surgery CFA measured just prior to dosing was decreased to 39.9%+/−13.2 SD (p<0.0001, n=8). SEQ ID NO: 868 was dosed at 258,000 U (0.5 g lyophilized powder) to bridge with the prior study, and at 86,000 U (167 mg) and 29,000 U (55.5 mg) to assess low dose efficacy. All doses evaluated resulted in a positive effect in CFA in a dose dependent manner. From high to low dose, CFA values increased to 81.3%+/−3.9 SD (p<0.0001, n=3), 74%+/−3.6 SD (p<0.0001, n=3), and 65.5%+/−3.7 SD (p<0.0001, n=2), respectively, compared to predose.
